How-to: Quickly Configure Kerberos for Your Apache Hadoop Cluster

Use the scripts and screenshots below to configure a Kerberized cluster in minutes.

Kerberos is the foundation of securing your Apache Hadoop cluster. With Kerberos enabled, user authentication is required. Once users are authenticated, you can use projects like Apache Sentry (incubating) for role-based access control via GRANT/REVOKE statements.

NYU, Analytics, and Cloudera’s QuickStart VM

The Cloudera QuickStart VM is an important platform for learning any Hadoop-related curriculum.

In the Fall 2013 semester, more than 30 NYU graduate students completed the Real-time and Big Data Analytics course at the NYU Courant Institute of Mathematical Sciences, for which I served as instructor.

How-to: Use Eclipse with MapReduce in Cloudera’s QuickStart VM

One of the common questions I get from students and developers in my classes relates to IDEs and MapReduce: How do you create a MapReduce project in Eclipse and then debug it?

To answer that question, I have created a screencast showing you how, using Cloudera’s QuickStart VM. The QuickStart VM helps developers get started writing MapReduce code without having to worry about software installs and configuration. Everything is installed and ready to go. You can download the image type that corresponds to your preferred virtualization platform.

Thanks for the Memories, #OSCON 2013

OSCON 2013 is already receding in the rear-view mirror, but we had a great time. Cloudera’s sessions were very well attended — with Tom Wheeler taking the prize (well over 200 attendees for his “Introduction to Apache Hadoop” tutorial) — but best of all was the opportunity to meet and mingle with people in the broader open source community. If you visited us at Booth 420, we hope you will now download and install the QuickStart VM after seeing it in our demo, and that your questions were adequately answered (most popular question: “Can you tell me more about Cloudera Impala?”)

In my biased opinion, the crowning achievement was our ability to not only distribute a couple hundred “Data is the New Bacon” Tshirts within a 36-hour period, but to clean ourselves out of the meat-free version shortly thereafter, as well:

QuickStart VM: Now with Real-Time Big Data

For years, Cloudera has provided virtual machines that give you a working Apache Hadoop environment out-of-the-box. It’s the quickest way to learn and experiment with Hadoop right from your desktop.

We’re constantly updating and improving the QuickStart VM, and in the latest release there are two of Cloudera’s new products that give you easier and faster access to your data: Cloudera Search and Cloudera Impala. We’ve also added corresponding applications to Hue – an open source web-based interface for Hadoop, and the easiest way to interact with your data.
